Best answer
Correct Answer - Option 1 : 273, 357

Given:

HCF = 21

LCM = 4641

Concept used:

Product of the numbers = LCM × HCF

Calculation:

LCM × HCF = 21 × 4641

The unit digit of the above product is 1. 

Let us go through the options.

In the options, we can see that except for option 1 the product of all other numbers has unit digit 0.

So, without calculating the actual product we can say that option 1 gives the two numbers.

∴ The numbers for the given LCM snd HCF from the given options is 273 and 357.
